(CNN) -- Oklahoma State University women's basketball coach Kurt Budke and assistant coach Miranda Serna were killed when their plane crashed on the way to a recruiting trip in Arkansas, university officials said Friday. 

Former Oklahoma state Sen. Olin Branstetter and his wife, Paula, also died in the crash Thursday, university spokesman Gary Schutt said. 

"It's a terribly sad day," he said. 

The crash occurred in Perry County, Arkansas, leaving no survivors. 

The plane, a Piper Cherokee PA-28, according to FAA records, crashed under "unknown circumstances" in a wooded area about four miles south of Perryville, Arkansas, about 4:30 p.m. CT on Thursday, agency spokesman Lynn Lunsford said Friday. 

No additional information about the crash was immediately available. 

The National Transportation Safety Board has sent investigators to the crash site, the agency said Friday. 

Budke and Serna were on a recruiting trip to Little Rock, Arkansas, the university said. 

"For any coaching community to lose bright stars like Kurt and Miranda is tragic," NCAA President Mark Emmert said in a statement. "This is a profound loss for the Oklahoma State women's basketball family, the entire university and future women's basketball players as well." 

University officials credited Budke for turning the school's women's basketball program around, culminating with a top-10 national ranking and an appearance in the second round of the NCAA tournament last season. He was in his seventh season with the school. 

"Kurt was an exemplary leader and a man of character who had a profound impact on his student-athletes," Oklahoma State President Burns Hargis said. "He was an outstanding coach and a wonderful person. We send our deepest sympathies to his wife, Shelley, and their children, Sara, Alex and Brett."

There once was a little monkey who lived in a zoo. He was a tiny brown monkey, smaller than all of the others. He was quieter than the others too. He was so quiet, in fact, that his mommy monkey made him wear a small blue bell around his neck so that she could find him. Even when the little monkey was very quiet, whenever he moved, the bell would jingle and his mother could find him. 

One day, this little monkey had been running around under the yellow sun for a long time, with his bell going "jingle jingle." He started to feel tired. But the other monkeys were still having fun and making a lot of noise. They were yelling and banging things together. The little monkey wanted to find somewhere quiet. 

Finally, he knew what to do: he took off his blue bell. He hung it on a branch. Then he sneaked out of his cage in the zoo. He waited. He was very quiet and small. He waited until a young girl came walking through the zoo. She was with her mother and father. Then he jumped into her red backpack. He was so small that she didn't know he was there. The girl and her mother and father got in their car and went home. 

When the girl got home, she set down her backpack. Her brother thought he saw her backpack moving. Her sister thought she heard something. But nobody knew that a tiny, sleepy monkey had come home from the zoo. He was happily sleeping in the girl's backpack in her quiet house, away from all the other noisy monkeys.

Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Antarctica is considered a desert, with annual precipitation of only 200 mm (8 in) along the coast and far less inland. The temperature in Antarctica has reached −89.2 °C (−128.6 °F), though the average for the third quarter (the coldest part of the year) is −63 °C (−81 °F). There are no permanent human residents, but anywhere from 1,000 to 5,000 people reside throughout the year at the research stations scattered across the continent. Organisms native to Antarctica include many types of algae, bacteria, fungi, plants, protista, and certain animals, such as mites, nematodes, penguins, seals and tardigrades. Vegetation, where it occurs, is tundra. 

Geologically, West Antarctica closely resembles the Andes mountain range of South America. The Antarctic Peninsula was formed by uplift and metamorphism of sea bed sediments during the late Paleozoic and the early Mesozoic eras. This sediment uplift was accompanied by igneous intrusions and volcanism. The most common rocks in West Antarctica are andesite and rhyolite volcanics formed during the Jurassic period. There is also evidence of volcanic activity, even after the ice sheet had formed, in Marie Byrd Land and Alexander Island. The only anomalous area of West Antarctica is the Ellsworth Mountains region, where the stratigraphy is more similar to East Antarctica. What are the answers to this following set of questions: 1. Which continent is the coldest?
2. The driest and windiest?
3. Which continent is generally more above sea level than Antarctica?
4. Does Antarctica get lots of snow?
5. Which is wetter, the coast or inland?
6. Are polar bears native to Antarctica?
7. What animals are?
8. Any others?
9. Can you name three others?
10. How many people live there?
11. Where do they live?

1. Antarctica

3. unknown
4. No
5. The coast
6. No
7. Mites
8. Yes
